Job Description

Senior Azure AI Document Intelligence Engineer (OCR Experience)

We are seeking a Senior Azure AI Document Intelligence Engineer responsible for designing, training, and optimizing AI-powered contract and invoice OCR solutions using Azure AI Document Intelligence, Azure Databricks, Azure Machine Learning, MLflow, Azure AI Search, OpenAI/GenAI, Python, and SQL , driving 98-99%+ extraction accuracy across complex supply-chain and procurement documents through advanced machine learning, document classification, validation frameworks, and intelligent automation.

Roles and Responsibilities:

Analyse invoice and contract variations across suppliers, countries, languages, formats, and scan-quality levels. Define the document taxonomy and extraction schema for: Invoice headers Contract metadata Purchase-order references

Supplier and customer information Dates, currencies, taxes, discounts, and totals Payment terms, renewal dates, obligations, and termination clauses Tables and invoice line items

Evaluate Azure AI Document Intelligence prebuilt invoice, layout, custom neural, custom template, classification, and composed-model capabilities.

Build and train custom document classifiers and extraction models. Prepare, label, clean, balance, and version training and evaluation datasets.

Implement document preprocessing for rotation, skew, noise, resolution, page separation, and scan-quality issues.

Develop confidence-scoring and validation strategies using field-level and OCR-level confidence signals. Implement deterministic validation rules, including Subtotal, tax, and total reconciliation Currency and date validation Purchase-order and supplier matching Duplicate-document detection

Required-field and cross-field consistency checks Establish confidence thresholds and human-review rules for uncertain extractions. Perform error analysis by document type, supplier, field, language, and scan quality.

Create automated evaluation pipelines reporting exact-match accuracy, precision, recall, F1 score, false-positive rates, and false-negative rates.

Monitor model drift and retrain models when document formats or business requirements change. Document model versions, training data, experiments, limitations, and release decisions. Collaborate with supply-chain, procurement, accounts-payable, legal, and engineering teams.
